OpenAI ships GPT-6.1 Sol Ultrafast across API and Codex

On October 8 local time, OpenAI released an Ultrafast version of GPT-6.1 Sol for developers, making it available in the API, Codex, and ChatGPT Work. Both 36Kr and IT之家 cited OpenAI Developers as the source of the announcement.

On performance and pricing, IT之家 reported that the Ultrafast version runs up to 8x faster than Sol Standard and is priced at 6x the standard rate. Both outlets gave the same figures: $12 per million input tokens and $60 per million output tokens. IT之家 also converted these to roughly CNY 80.5 per million input tokens and CNY 402.7 per million output tokens at the exchange rate at the time.

Regarding availability, IT之家 said the Ultrafast version has rolled out in all supported regions and fully supports data residency compliance services in the United States and the European Union. Within Codex and ChatGPT Work, it is available to Pro 500, eligible usage-based Enterprise plans, and credit-based Edu plans, with enterprise users required to have an administrator enable the permission. The 36Kr report did not mention the speed multiple or the availability scope, noting only that the version had launched in the API, Codex, and ChatGPT Work along with its pricing. Public information currently stops at this release and its availability arrangements.
